Yay, interested parties!
Always great to meet fellow Suikoden fans as well!
If you think it would be more fun to make an alt for this concept, I certainly won't stop you! But I should also mention that a character doesn't have to be involved in both the Stars of Destiny plot and the running of the Host Club. For example, someone who has a mark of destiny could just use the Host Club building as a general place of gathering with the others who are connected, and leave the running of the club to the others. (Depending on IC motivations.) Conversely, if someone only wants to be a staffer of the Host Club but they don't want their characters to have a mark and be involved in the 'connected by fate' aspect, that's fine, too.
There is an IC reason that D'ranmaia owns a Host Club building (not officially opened yet), and she will also happen to be a Star of Destiny. As such, she would gladly offer the building toward the purpose of gathering the Stars, though she is also ICly motivated to open the club for [recent backstory reasons.] So basically, it can be a combination of however you want your character to fit into the setting, along with how your character would react to this scenario. (I think it would also be funny to have some people working at the Host Club who are just really bad at it, for comedy's sake.)
At the end of the day, the main idea is to break down the FC silos and have fun RPing together under a cohesive and all-inclusive plot/setting. I know there are inevitably other linkshells who serve this purpose as well, but I feel that I could tell an interesting story and set up some pretty entertaining character scenes with this one. ^^
